This invention relates to dispensing device and more particularly to a device for dispensing liquids.

The object of the invention is to provide an improved and simplied liquid dispenser which permits a selective range both in the amount dispensed and the direction of application and is particularly useful in connection with the dispensing of disinfectants and the like.

The invention consists in the novel construction arrangement and combinations of parts as hereinafter more particularly described and claimed.

One sheet of drawings accompanies this specication as part thereof in which like reference characters indicate like parts throughout.

In the drawings:

Fig. l is a side elevation, partly in cross section;

Fig. 2 is a fragmentary view of the upper end of the standard shown partly in cross section;

Fig. 3 is a vertical transverse cross section through a modified form of the invention; and

Fig. 4 is a longitudinal cross section through the intake check valve.

The present invention is directed to a dispensing device for liquids and more particularly chemicals, and various parts can. be constructed of suitable materials, metals, plastics or the like, as may appear desirable in connection with the particular liquid to be dispensed.

In accordance with the present invention, a container I is provided as a reservoir for the liquid to be dispensed, having a compartment 2 and as herein illustrated a removable cover 3 with a threaded orifice and cap 5 through which additional liquid can be introduced.

A tubular standard 8 is passed through the cover 3 and secured thereto as by a threaded ring l secured on the standard 8 and engaging a similarly threaded orifice in the cover. The bottom of the standard 8 is steadied by being inserted in a circular flange 6 formed on the bottom of the container.

The upper end of the standard 8 is closed by a cap 9, a portion of which extends within the tube 8 and is provided with an annular groove I0 within which a screw I I threaded through the standard 8 is adapted to engage, thus permitting rotation of the cap with respect to the standard but preventing sliding movement of the cap except C `fllarry iljireifenbach, Glen Olden, Pa. f

Application January 27, 19'48, Serial No. 4.623

this passage I2 is threaded one end of a dispensing tube 26 which is preferably bent to extend at an angle with respect to the standard 8.

The tube I3 extends downwardly through the standard 8 and through a lateral orifice I4 adjacent the bottom of the standard and is connected with an inlet check valve positioned within the compartment 2 and adjacent the bottom of the container I. The inlet check Valve 40 is further connected with an additional tube I3' which extends through a Wall of the container and has secured on its outer end a compressible bulb I5.

The check valve 40 is of conventional construction comprising a body having a through orice with two valve seats 28 and 38' with which valve seats are associated balls 28 and 30, the arrangement being such that upon compression of the bulb I5 liquid will be forced through the tube I3 and through the outlet discharge tube 26. Release and expansion of the bulb I5 introduces a new charge of liquid. from the container through the inlet port 2l.

Supported by the container is a housing for the compressible bulb I5, comprising a bottom I6 and a hinged wall or cover I'I pivoted with respect to the container as by pivots I8. The rocking of the pivoted cover Il may be controlled by set screws 2I threaded through flanges 28 formed on the housing and engaging lugs I9 formed on the cover I'I.

With the structure thus described and illustrated in Fig. 1, it will be apparent that the discharge tube 26 is disposed annularly with respect to the standard 8 in any direction as desired and that pressure of the foot upon the hinged lid II will ,cause the discharge of a predetermined amount of the liquid through discharge pipe 26.

where it is desired to remove the cap which is permissible by removal of the screw II. The cap 9 has an axial orice I2 within which is rotatably seated the upper end of a tube I3 and in In the modiiied form of the invention illustrated in Fig. 3, the container is formed With a back Wall 3| in the form of a bracket adapted to be secured to a Wall and the housing for the compressible bulb I5 is preferably located below the bottom of the container I so that the hinged cover I1 can be manipulated by hand. In this form of the invention, the tube I3 is extended directly through the bottom of the container and functions as a discharge port.

Various modifications in the precise arrangements and construction of the parts will readily suggest themselves to those skilled in the art but Within the scope of the invention as claimed.

Having thus fully described my invention, I claim:

Liquid dispenser comprising a container, a disand bulb, an inwardly opening check valve controlling said opening, a hinged operatingplate sustained in normal inactive position bysaid bulb, and an adjustable stop spaced from that side of said plate which is in contactwith said bulb, in the path of movement thereof, to be contacted by said plate for determining the amount of liquid displaced by said bulb when said plate is pressed against said bulb.
